Most of the top colleges have diploma and certificate courses in counselling, which needs one to be a graduate.

You may clear your tybcom exams and then opt for a good institute. There are options for distance course in counselling too.

However, kindly note that it is important to do a regular course to understand the basics of counselling, since you do not have a background in counselling topics. If you take a distance study option, like IGNOU, you should read the books recommended by the university to get your basics right.
